XRP7714ILBTR-0X18-F

Overview

The XRP7714ILBTR-0X18-F is a specialized digital power management IC from the PowerXR series, manufactured by MaxLinear. It features a quad-channel digital PWM controller architecture housed in a 40-pin TQFN package with an exposed pad. The device operates within an input voltage range of 4.75 V to 25 V and supports output voltages adjustable from 900 mV to 5.1 V. It integrates programmable buck regulators with a switching frequency of 1.5 MHz and includes an LDO for auxiliary power. The component is designed for surface mount installation and functions reliably across a temperature range of -40°C to +125°C.

Feature Summary

• Digital control interface via I2C for precise configuration
• Quad-channel synchronous buck regulation topology
• Integrated low-dropout regulator (LDO) output
• Programmable sequencing and monitoring capabilities

Applications

• Multi-rail power distribution in networking equipment
• Power systems for industrial control boards
• Embedded computing platforms requiring synchronized rails

Procurement Notes

Verify the specific suffix '0X18' against official MaxLinear documentation, as it indicates a custom or customer-specific variant distinct from standard commercial parts. Confirm current lifecycle status, as many components in this series are marked obsolete. Ensure compatibility with existing PCB footprints and programming tools before procurement.

Selection Notes

Select this component when a compact, digitally controlled multi-output solution is required for space-constrained designs. It is suitable for applications needing independent voltage adjustment and synchronization between multiple power rails. Consider the thermal performance of the TQFN package and the availability of development kits for initial validation.

Part Context

This part belongs to the XRP7714 family of digital power controllers, which are engineered for high-density power delivery. The series is commonly utilized in infrastructure and communication hardware where efficient power conversion and digital manageability are critical. It represents a shift from analog to digital control for enhanced flexibility.

Replacement Considerations

Check for direct substitutes within the XRP77xx series or updated generations such as the XR77128. Verify pin-to-pin compatibility and software register mapping if migrating to newer digital PMICs. Consult MaxLinear for obsolescence notices and recommended transition paths.
